EPR of Mn2+ in Strontium Tartrate Trihydrate Single Crystals

Abstract

AbstractElectron paramagnetic resonance spectra of Mn2+ doped in single crystals of strontium tartrate trihydrate grown by a diffusion technique are investigated at room temperature. Mn2+ enters the lattice substitutionally and is trapped at two magnetically equivalent but crystallographically inequivalent sites. The EPR measurements give the following values for the spin‐Hamiltonian parameters: gx(= gy) = 1.9781, gz = 2.0012, Ax(= Ay) = −94.9 × 10−4 T, Az = −96.2 × × 10−4 T, BB(= D/3) = +160.9 × 10−4 T, B(= E) = +101.2 × 10−4 T, B = +0.013 × 10−4 T, and B = +0.088 × 10−4 T.
